DAISLIDE
DAISLIDE is a copper-based self-lubricating bearing for heavy load applications into which solid lubricant plugs are embedded.
Product Details
Features
- Maintenance-free.
- Excellent wear resistance in applications where oil film formation is difficult such as reciprocating, intermittent or oscillating motions under high loads and low speeds.
- Low friction.
- Range of operating temperatures.
- Freedom of design on shape and the size.
- Excellent corrosion and chemical resistance. This bearing can be used in river or sea water; in liquids where chemical resistance of the metal base and solid lubricant is needed; and in gas where oil supply is difficult.
- Excellent impact resistance.
Major Applications
General industrial machinery and heavy industrial facilities
Characteristics
| Specific Load MPa | Sliding Speed m/min | Service temp. Range °C (Min. to Max.) | Friction Coefficient μ | Tolerance of Foreign Particles | ||
|---|---|---|---|---|---|---|
| Normal | Max | Normal | Max | |||
| Below 19.6 | 49.0 (98.0) | Below 6 | 30 | -70～250 | 0.05～0.3 (Boundary Lubrication) | Medium |
- On the actual application, the best performance in all categories would not be expected to be exerted simultaneously.
- Thermalloy, Daislide and Dailubo have general-to-special grades to meet various customer needs.
